There doesn't seem to be any way that 'comment' could be null in your
current patch, since svn_stringbuf_from_file2() promises to return "a
string". (But maybe you will make the comment optional in a subsequent
patch.)

Instead of 'comment' and 'strlen(comment)' you could use
file_contents->data and file_contents->len. That would also catch the
case where there's a null character in the file.

Don't get the youngest revnum ...

... because that will only make this call fail if there's a commit
happening at the same time, where otherwise this would succeed. Just
pass SVN_INVALID_REVNUM.
